Question

Part A

A certain reaction has an activation energy of 67.0 kJ/mol and a frequency factor of A1 = 1.40×1012 M−1s−1 . What is the rate constant, k, of this reaction at 28.0 ∘C ? Express your answer with the appropriate units. Indicate the multiplication of units explicitly either with a multiplication dot (asterisk) or a dash.
